Problems:

Overheating

The cooling systems in older models like the 1990 Volkswagen Jetta may become less efficient over time, leading to overheating issues.

Oil leaks

Gaskets and seals can degrade over time, leading to oil leaks which are common in older engines.

Timing belt failure

The timing belt needs regular replacement as it can wear out and break, causing significant engine damage if not addressed.

Worn piston rings

With age and mileage, piston rings can wear out, leading to decreased compression and increased oil consumption.

Fuel injector problems

Fuel injectors can get clogged or fail, leading to poor engine performance and reduced fuel efficiency.

Ignition system issues

Components like spark plugs, ignition wires, and the distributor cap can wear out, causing misfires and starting problems.

Vacuum leaks

Hoses and seals can deteriorate, leading to vacuum leaks that affect engine performance and fuel economy.
